Everything on Software Architecture & Security

Git 3.0 will mandate Rust compiler integration and transition the default hashing algorithm from SHA-1 to SHA-256, addressing memory safety and cryptographic collision risks.

Impact: Enterprises must update CI/CD pipelines and ensure Forge compatibility to prevent deployment failures and maintain secure, auditable code histories.
